Helpful Notes:
- This memory kit is designed for use in servers and workstations that require ECC registered memory.
- DDR2 memory is slower and less power-efficient than DDR3 and DDR4 memory, but may still be necessary for older systems.
- Dual rank memory modules provide better performance than single rank modules, but may not be compatible with all systems.
